One Risk Factor (one + risk_factor)
Kinds of One Risk Factor Selected AbstractsColesevelam lowers glucose and lipid levels in type 2 diabetes: the clinical evidenceDIABETES OBESITY & METABOLISM, Issue 5 2010Vivian A. Fonseca Simultaneous control of blood glucose and other risk factors such as hypertension and dyslipidaemia is essential for reducing the risk of complications associated with type 2 diabetes mellitus (T2DM). As relatively few patients with T2DM have their risk factors managed to within the limits recommended by the American Diabetes Association, American College of Endocrinology or National Cholesterol Education Program Adult Treatment Panel III guidelines, treatment that can simultaneously control more than one risk factor is of therapeutic benefit. Clinical studies have shown that bile acid sequestrants have glucose-lowering effects in addition to their low-density lipoprotein cholesterol-lowering effects in patients with T2DM. The bile acid sequestrant colesevelam hydrochloride is approved as an adjunct to antidiabetes therapy for improving glycaemic control in adults with T2DM. This review examines data from three phase III clinical trials that evaluated the glucose- and lipid-lowering effects of colesevelam when added to the existing antidiabetes treatment regimen of patients with T2DM. [source] NSAID-related upper gastrointestinal bleeding: are risk factors considered during prophylaxis?INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 5 2006D. Dincer Summary The purposes of this study were to evaluate the effect of nonsteroidal anti-inflammatory drugs (NSAIDs) on acute nonvaricose upper gastrointestinal bleeding (ANUGIB) and establish whether the NSAID-prescribing physicians take precautions to prevent or reduce GI ulcerations. Clinical characteristics, causes of bleeding and clinical outcomes of patients hospitalised in our gastroenterology clinic with ANUGIB were recorded prospectively over a 1.5-year period. NSAIDs, including aspirin, were used by 127 of 168 patients (73%). Among the NSAID users, 100 patients (78%) had at least one risk factor for serious adverse GI events related to NSAIDs. Only two patients were using proton pump inhibitors and one patient was using H2 receptor blocker of the high-risk group for GI side effects of NSAIDs. NSAIDs have an important effect on GI bleeding, and it seems that risk factors are underestimated by physicians. [source] Use of antisecretory drugs among consumers of non-steroidal anti-inflammatory drugs in the general populationALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 11-12 2006E. REY Summary Background, Overall success of prophylactic strategies against non-steroidal anti-inflammatory drug (NSAID) complications depends on the use of gastroprotective drugs. Aim, We examined the use of antisecretory drugs in NSAID users in the general population of Spain. Participants and Methods, In 2002, a phone interview was conducted with 2500 persons representative of the general population of Spain. Using a validated questionnaire, we asked about the use of NSAID, aspirin and antisecretory drugs, and history of digestive diseases. We estimated the use of antisecretory drugs in NSAID users, according to risk factors for gastrointestinal (GI) lesions associated with NSAID. Results, In total, 425 persons [17.0% (95% CI 15.5,18.5%)] were NSAID users. Of them, 69 persons (16.2%; 95% CI 12.7,19.7%) used antisecretory drugs [proton pump inhibitor (PPI) 11.8% and H2-blocker 4.9%]. Forty-four of the 224 NSAID users (19.6%) with one risk factor for GI lesions were antisecretory drug users (PPI 16%; H2-blocker 4%), compared with 24 of the 197 NSAID users (12.7%) without risk factors (PPI 6.6%; H2-blocker 6.1%). NSAID users with risk factors for GI lesions but without upper GI (UGI) symptoms did not consume more antisecretory drugs than equivalent non-NSAID users (12.9% vs. 10.7%). Conclusion, Current strategies to prevent GI lesions in NSAID users are not effective from a population perspective, especially in subjects without UGI symptoms. [source] Peripheral neuropathy associated with leflunomide: is there a risk patient profile?,PHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 1 2007Karin Martin pharmD Abstract Purpose (i) To monitor the potential clinical neurotoxic symptoms in patients treated with leflunomide in daily practice and (ii) to describe the characteristics of patients presenting with this peripheral nervous system symptoms. Method All patients treated with leflunomide between May 2000 and April 2003 and followed in the rheumatology department of the University Hospital participated in the study. Data concerning treatment patterns with leflunomide, demographic and disease characteristics were obtained from clinical charts. Neuropathy was diagnosed with nerve conduction study (NCS). Cases of neuropathy were described and then compared to other patients using univariate analyses. Results One hundred and thirteen patients were included in the study. M/F sex ratio was 0.45. Mean age at start of treatment was 55.6 years (range,=,27,81). During the study period, eight incident cases of peripheral neuropathy and two cases of worsening of preexisting neuropathy were reported (incidence: 9.8%). Compared with other patients, neuropathy cases were older (69 vs. 54 years, p,=,0.0006), more often diabetic (30% vs. 2.9%, p,=,0.009) and more often treated with potentially neurotoxic drugs (20% vs. 1.9%, p,=,0.039). At least one risk factor (potentially neurotoxic drug or diabetes) was found in 50% of patients with neuropathy versus 4% of patients without neuropathy (56% PPV, 96% NPV). Conclusion Cases of toxic neuropathy have been observed during treatment of rheumatoid arthritis with leflunomide. Their occurrence seems to be associated with known risk factors. Careful monitoring of the patient's neurological status during leflunomide treatment is therefore mandatory. Copyright © 2006 John Wiley & Sons, Ltd. [source] Latest news and product developmentsPRESCRIBER, Issue 6 2007Article first published online: 8 JUN 200 Initial macrolide better for pneumonia? An observational study has suggested that initial treatment with a macrolide antibiotic (such as erythromycin) may be more effective than a fluoroquinolone (like ciprofloxacin) or tetracycline as initial treatment for community acquired pneumonia and bacteraemia (Chest 2007;131:466-73). The US review of 2209 hospital episodes found that macrolide therapy was associated with a 40 per cent lower risk of death during hospital stay or within 30 days and of hospital readmission within 30 days of discharge. By contrast, no such benefit was apparent with fluoroquinolones or tetracycline. Two-year safety data for inhaled insulin Compared with sc insulin, inhaled insulin (Exubera) is associated with a small early decrease in lung function in the first three months of therapy but no further difference for up to two years (Diabetes Care 2007;30: 579-85). The comparative trial found that FEV1 declined at a mean rate of 0.051 litres per year with inhaled insulin and 0.034 litres per year with sc insulin, but there was no significant difference in the rates of decline after three months. Inhaled insulin was associated with a higher incidence of cough (37.6 vs 13.1 per cent) but a lower incidence of severe hypoglycaemic events (2.8 vs 4.1 events per 100 subject- months) and mean weight gain was 1.25kg less. Fracture risk warning with rosiglitazone GlaxoSmithKline has warned US prescribers that rosiglitazone may be associated with an increased risk of fractures. The company says information for prescribers in Europe will follow shortly. The warning comes from the ADOPT study (N Engl J Med 2006;355:2427-43), which found a significantly higher incidence of fractures of the humerus, hand and foot among women taking rosiglitazone (9.3 per cent) than with metformin (5.1 per cent) or glibenclamide (3.5 per cent). There was no difference in fracture incidence among men. The company recommends that fracture risk should be considered for women taking or about to take rosiglitazone. Oral treatment for grass pollen allergy A new treatment for allergic rhinitis due to grass pollen allergy has been introduced by ALK-Abelló. Grazax is a sublingual tablet containing a stan-dardised dose of allergen from the pollen of timothy grass. Treatment should be initiated by a specialist four months before the onset of the allergy season and continued throughout the season. Adverse effects include oral and ear pruritus, nasopharyngitis and mouth oedema. A month's treatment at the recommended dose of one tablet daily costs Ł67.50. Frequent analgesics linked with hypertension Men who take analgesics regularly have an increased frequency of hypertension, a US study has shown (Arch Intern Med 2007;167:394-9). The US Health Professionals Follow-Up study evaluated the use of NSAIDs, paracetamol and aspirin in 16 031 men with normal blood pressure and followed them up for four years. Compared with those who did not report analgesic use, the risk of hypertension was increased by 38 per cent for NSAID use, 34 per cent for paracetamol and 26 per cent for aspirin, all for for six or seven days a week. Similar risks were found when anal- gesic use was determined according to the number of tablets taken. The authors acknowledge the increased risk is modest, but point out that the implications may nonetheless be important because analgesics are widely used. Multiples do most pharmacist MURs Uptake of medicines use reviews (MURs) by pharmacists was modest in 2005 and most reviews were carried out by pharmacy chains rather than independent contractors, a new study has shown (Pharm J 2007;278:218-23). The survey of PCTs and SHAs in England and Wales found that, although 38 per cent of community pharmacies claimed payments for the service, 84 per cent of MURs were carried out by pharmacy chains. Uptake was low, amounting to only 7 per cent of the maximum possible number of MURs. Patients see information needs differently There is a mismatch in the perceptions of patients and health professionals about the purpose of written information about medicines, a systematic review has concluded (Health Technol Assess 2007;11:1-178). Some health professionals believe the main purpose of information is to promote compliance, whereas patients want information to help them make decisions about their treatment, including not taking it. In particular, patients want information on adverse effects, but health professionals have reservations about providing it. Aspirin for all women over 65? All women over 65 should take low-dose aspirin if the benefits are likely to outweigh the risk of adverse effects, according to new guidelines from the American Heart Association on preventing cardiovascular disease in women (published online 19 Feb 2007;doi: 10.1161/circulationaha.107.181546). The guidelines have moved away from the long-established Framingham model of risk assessment to categorising three levels of risk: high (heart disease or other relevant disease present), at risk (at least one risk factor) and optimal (healthy lifestyle, no risk factors). Low-dose aspirin is recommended for all women at high risk, for women aged 65 or over when reducing the risk of MI or ischaemic stroke outweighs the risk of adverse effects, and for younger women when reducing the risk of ischaemic stroke outweighs that of toxicity. Combination inhaler therapy Combining an inhaled long-acting bronchodilator with a steroid reduces COPD exacerbations but not all-cause mortality, a three-year trial has shown (N Engl J Med 2007;356:775-89). However, inhaled steroids appear to increase the risk of pneumonia. The TORCH trial randomised 6112 patients (FEV1<60 per cent predicted) to treatment with salmeterol 50µg plus fluticasone 500µg (Seretide) twice daily, salmeterol (Serevent) or fluticasone (Flixotide) as monotherapy, or placebo. All-cause mortality rates were 12.6, 13.5, 16.0 and 15.2 per cent respectively; the risk of death was 17 per cent lower with combined therapy, but the difference did not reach statistical significance. The combination reduced the incidence of exacerbations by 25 per cent and improved health status and FEV1. Use of fluticasone was not associated with more ocular or bone disorders, but there was an increased incidence of pneumonia among users (19.6 per cent with combined therapy and 18.3 per cent with fluticasone vs 12.3 per cent with placebo). Seretide is currently licensed in the UK for use in patients with FEV1 <50 per cent predicted. Tamoxifen long- term benefits Women with breast cancer who take tamoxifen for five to eight years continue to have a lower risk of recurrence for 10-20 years, long-term follow-up of two blinded trials has shown (J Nat Cancer Inst 2007; 99:258-60, 272-90). The frequency of adverse effects was markedly reduced when treatment ended, changing the balance of risk and benefit. Copyright © 2007 Wiley Interface Ltd [source] Osteoporosis risk in a home care settingAUSTRALASIAN JOURNAL ON AGEING, Issue 2 2009Joanna Smith Aim:, To investigate the osteoporosis risk profile of older home care clients and the prevalence of fracture and treatment within this group. Methods:, A total of 1500 home care clients were randomly selected and mailed a survey. Overall, 874 (58%) of those surveyed completed and returned the survey. Results:, A third (37%, n = 318) reported at least one fracture and 871(99.7%) reported at least one risk factor for osteoporosis. Despite this only 28% reported a diagnosis of osteoporosis, which was more likely if they had sustained a fracture. Bone mineral density tests were reported by 37.4% of respondents and 51.9% of those who had fractured. Only 34.5% who had fractured had been referred for an osteoporosis assessment following their fracture. Conclusions:, The home care clients surveyed have many of the risk factors associated with osteoporosis and fracture. A large number reported that they had already sustained fractures that can be attributed to osteoporosis. Despite this, a minority have been assessed or treated for osteoporosis. [source] Debunking the ,only 50%' myth: prevalence of established risk factors in New Zealanders with self-reported ischaemic heart diseaseAUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 5 2005Martin Tobias Objective: To estimate the prevalence of established risk factors for ischaemic heart disease (IHD) in New Zealand adults and compare the prevalence in adults with and without this disease. Design: Data were obtained from the 2002/03 New Zealand Health Survey. Risk factor prevalence was determined by: selfreported doctor diagnosis of high blood pressure, high cholesterol and diabetes; self-report of smoking and physical inactivity; and measurement of obesity. Presence of IHD was based on self-report of heart disease (doctor diagnosed at age 25 years or over) together with current medical or past surgical treatment for this disease. Multiple logistic regression was used to determine prevalence rate ratios (PRRs) for males and females separately, adjusting for age, ethnicity and deprivation. Results: The overall prevalence of IHD was 8%. Overall risk factor prevalences were in the range of 20,25% for each of high blood pressure, high cholesterol, smoking, obesity and physical inactivity, and approximately 5% for diabetes. Overall, 94,97% of adults with IHD had at least one risk factor (depending on how smoking was defined). The PRRs of IHD were highest for cholesterol (about 4.5), followed by blood pressure (about 2.3), with all other risk factors around 1.5. PAF estimates indicate that 80,85% of IHD was attributable to the presence of at least one risk factor for all age, gender and ethnic groups. Conclusions: Established risk factors account for 80,85% of the non-fatal burden of IHD in New Zealand. Limited research resources would be better used to evaluate which interventions are effective and efficient at reducing exposure of all population groups to known risk factors, rather than on identification of additional risk factors. [source] Selection bias in Teratology Information Service pregnancy outcome studiesBIRTH DEFECTS RESEARCH, Issue 2 2001K. A. Johnson Background Pregnancy outcome studies conducted through Teratology Information Services (TIS) rely on volunteer subjects. If these subjects tend to have different risk profiles than the population from which they are drawn, the results of TIS studies may have limited generalizability. Methods We selected all subjects who enrolled in the California Teratogen Information Service (CTIS) pregnancy outcome study for prenatal exposure to carbamazepine or valproic acid between 1990 and 1997 and who received prenatal care through Kaiser Permanente of Southern California (n = 13). We compared these subjects to Kaiser patients identified through the Maternal Serum Alpha Fetoprotein Program with exposure to carbamazepine or valproic acid but who had not enrolled in the CTIS project. The controls were matched by Kaiser location and pregnancy year using a 2:1 ratio (n = 26). Medical records were reviewed and the prevalence of 14 pregnancy risk factors was compared between the two groups. Results There were no significant differences between the groups on any one risk factor; however, a notably higher proportion of women who did not enroll in the CTIS study used tobacco or had a positive family history of congenital anomalies. Conclusions Although the sample was small, and results may not apply to other exposures in different health care environments, these data provide some evidence that women who enroll in TIS pregnancy outcome studies do not have a substantially different pregnancy risk profile than women who do not. Efforts to address possible selection bias should be incorporated in future TIS study design. Teratology 64:79,82, 2001. © 2001 Wiley-Liss, Inc. [source] Expression of potential molecular markers in renal cell carcinoma: impact on clinicopathological outcomes in patients undergoing radical nephrectomyBJU INTERNATIONAL, Issue 7 2009Iori Sakai OBJECTIVES To evaluate the expression levels of several potential molecular markers in renal cell carcinoma (RCC), to clarify the significance of these markers as prognostic predictors in patients undergoing radical nephrectomy (RN). PATIENTS AND METHODS The study included 153 patients with clinically organ-confined RCC undergoing RN. Expression levels of 12 proteins, including Aurora-A, Bcl-2, Bcl-xL, clusterin, heat-shock protein 27 (HSP27), HSP70, HSP90, Ki-67, matrix metalloproteinase (MMP)-2 and -9, p53 and vascular endothelial growth factor, in RN specimens obtained from these 153 patients were measured by immunohistochemical staining. RESULTS Of the 12 markers, clusterin, HSP27, Ki-67, MMP-2 and -9 expression were significantly associated with several conventional prognostic factors. Univariate analysis also identified these five markers as significant predictors of disease recurrence, while mode of presentation, pathological stage, grade and microvascular invasion were also significant. Of these significant factors, Ki-67 expression, pathological stage and microvascular invasion appeared to be independently related to disease recurrence. Furthermore, there were significant differences in recurrence-free survival according to positive numbers of these three independent factors, i.e. disease recurred in four of 56 patients who were negative for risk factors (7%), 17 of 71 positive for one risk factor (24%), and 20 of 26 positive for two or three risk factors (77%). CONCLUSIONS Combined evaluation of Ki-67 expression, pathological stage and microvascular invasion would be particularly useful for further refinement of the system for predicting the outcome after RN for patients with RCC. [source] An audit of eccentrically-positioned ruthenium plaque radiotherapy of choroidal melanoma in LiverpoolACTA OPHTHALMOLOGICA, Issue 2009A RUSSO Purpose Brachytherapy is usually administered with the plaque overlapping the entire tumour margin by at least 1-2mm. With posterior tumours, our practice is to position the plaque with its posterior edge aligned with the posterior tumour margin. We audited ocular outcomes after eccentrically-placed ruthenium plaque radiotherapy of choroidal melanoma. Methods Patients were included if receiving primary ruthenium brachytherapy for choroidal melanoma during the three years up to the 31st July 2007. A perforated template was used to facilitate plaque positioning. For posterior tumors, the template was positioned so that trans-illumination produced a glow at the posterior tumour margin (,sunset sign'). Minimum doses of 300-350 Gy and 80-90 Gy were prescribed to the sclera and apex, respectively. Results The cohort comprised 162 patients (93 female and 69 male). The time to the last known visual acuity had a median of 23 months. The initial visual acuity was 20/40 or better in 94.6%, 20/60 to 20/200 in 13.0% and worse than 20/200 in 1.9% of patients. The tumours had a mean basal diameter of 11.7mm. Ten tumours exceeded 5.4 mm in height. Tumour extension to within 5mm of optic disc, fovea or both occurred in 18 (11.1%), 28 (17.3%) and 27 (16.7%) cases respectively. Risk factors for visual loss were proximity to optic disc or fovea, initial visual acuity worse than 20/40 and tumour height exceeding 5.4 mm. In 66 patients with none of these risk factors, 92% retained 20/40 or better and 5 had vision of 20/60 , 20/200. In 72 with one risk factor, 74.3% retained 20/16 , 20/40 and 95.7% had vision of 20/200 or better. In 12 patients with 2 risk factors, these percentages were 25.0% and 91.7%. Only 3 patients had 3 risk factors and one retained vision of 20/200 or better. Tumours distanced < 5 mm to fovea were divided in 3 groups, and visual acuity analysed. Three patients had local tumour recurrence and were treated respectively by proton beam radiotherapy, plaque radiotherapy and enucleation (the only eye lost in this series). Conclusion Eccentric plaque radiotherapy of choroidal melanoma achieves good rates of local tumour control, ocular retention and preservation of vision. [source] Homocysteine levels in patients with risk factors for atherosclerosisCLINICAL CARDIOLOGY, Issue 6 2001Arnon Blum M.D. Abstract Background: Abundant epidemiological evidence has demonstrated that the presence of mild to moderate hyperhomocysteinemia is an independent risk factor for atherosclerosis in the coronary, cerebral, and peripheral vasculature, and for vascular disease, including coronary disease. It has been demonstrated that plasma total homocysteine level is a strong predictor of mortality in patients with angiographically confirmed coronary artery disease. Hypothesis: The study was undertaken to determine the extent of homocysteine levels in patients without documented coronary artery disease, but with at least one risk factor for atherosclerosis. Methods: Fasting blood samples were collected prospectively from 160 consecutive patients (50 women and 110 men, mean age 65 ± 7 years) who had at least one risk factor for atherosclerosis, but had no documented coronary artery disease. Homocysteine levels were measured by an immunoassay method. Results: Of the patients studied, 78 (48.75%) with at least one risk factor for atherosclerosis had high homocysteine levels; 62 patients had mild hyperhomocysteinemia (15,30 ,mol/l); and 16 patients had moderate hyperhomocysteinemia (30,100 ,mol/l). Conclusions: Our data suggest that hyperhomocysteinemia is highly prevalent in patients with risk factors for atherosclerosis. Homocysteine level (an independent convertible risk factor to atherosclerosis) should be measured routinely in patients with risk factors for atherosclerosis and treated appropriately. [source] |
